An impedance analyzer is a type of electronic test equipment used to measure complex electrical impedance as a function of test frequency. Impedance is an important parameter used to characterize electronic components, electronic circuits, and the materials used to make components. Impedance analysis can also be used to characterize materials ...
Measures Resistance of an Winding of Motor or Generator And Measures Earthing's Resistance Microwave power meter: Measures power at microwave frequencies Multimeter: General purpose instrument measures voltage, current and resistance (and sometimes other quantities as well) Network analyzer: Measures network parameters Ohmmeter
Techniques and devices involving the measurement of electrical impedance or at least one of its components (resistance, capacitance, inductance), potentially taking into account distance (e.g. resistivity).
Q meter Tesla BM 560. A Q meter is a piece of equipment used in the testing of radio frequency circuits. It has been largely replaced in professional laboratories by other types of impedance measuring devices, though it is still in use among radio amateurs.
A LISN provides a measurement port with, usually, 50 Ω output impedance. [3] The stabilized impedance, the built-in low-pass filter function, and the DC rejection properties of the LISN measurement port makes it easy to couple the high frequency noise signal to the input of the measuring equipment. [4]
An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value. Readings should be reasonably ...
Ohmmeter (Measures resistance) Ammeter, e.g. Galvanometer or Milliammeter (Measures current) Multimeter e.g., VOM (Volt-Ohm-Milliammeter) or DMM (Digital Multimeter) (Measures all of the above) LCR meter - inductance (L), capacitance (C) and resistance (R) meter (measure LCR values) The following are used for stimulus of the circuit under test:
The internal resistance of the coil is decoupled from the selection of the series and shunt range resistors; the series network thus becomes a voltage divider. Where AC measurements are required, the rectifier can be placed after the amplifier stage, improving precision at low range.
